Humming To Snails

The common periwinkle is a gastropod found from the Bay of Fundy to New Jersey, and extending to Europe. They are about the size of a hershey kiss and eat the algae and moss that are on rocks. There are many tales that humming to the snail will make it emerge from its shell. The theories are that the vibration of the hum entices the snail to come out or that it is relaxing for the snail. Research has been attempted to explore this idea. The results from the research have been inconclusive, and the only clear thing at the moment is to believe that patience is the only key to making a snail emerge from its shell.
